the invention aims to provide a flap oiE the joint formed by the overlapped ends of the class described which will be simple to band 6 being disposed between the joints 5o manufacture and be well .adapted to with- 5 of the layers l .and 2, circumferentially stand severe use, the lap being so conof the flap. The band 6 is narrower than structed that it will aord a cushion for the the layers 1 and 2, and the layers l and 2 10 inner tube. are vulcanized together, as shown at 8, on

It is within the province of the disclosure each side of the band 6. The flap has the to improve generally and to enhance the usual hole l0 for the reception oi a valve utility of devices of that type to which the stem. rlhe band 6 of iibre compound serves invention appertains. as a cushion for theinner tube (not shown) Nith the above and other objects in view and protects it from the metal rim of an which will appear as the description proautomobile Wheel.
